How do I report terrorism?
Terrorism is a crime - if you suspect it, report it. Do not rely on others.
If it’s an emergency and you suspect an immediate danger call 999.
You can report it online to:
or call the confidential Anti-Terrorism Hotline on 0800 789 321. This service is monitored 24 hours a day.
Let the police decide if the information is important. What might seem insignificant on its own could actually provide a vital link to a wider investigation.
